What is ISO 3087 about?
ISO 3087 is an international standard on iron ores. ISO 3087 specifies a method for the determination of the moisture content of a lot of iron ore. This method applies to all iron ores, whether natural or processed.
NOTE: ISO 3087 does not address the determination of the hygroscopic moisture content of a test sample for chemical analysis. If the hygroscopic moisture content is required to be determined, reference should be made to ISO 2596:2006.
Who is ISO 3087 for?
ISO 3087 on iron ore is relevant to:
- Iron ore Industries
- Iron ore testing laboratories
Why should you use ISO 3087?
Currently, large tonnages of iron ore are traded internationally and a small error in the measured moisture content [mass fraction (%)] of a lot has a considerable effect on the commercial transaction. The correct determination of moisture content of a lot is, therefore, a matter of importance for both the purchaser and the vendor.
ISO 3087 provide guidance regarding apparatus, samples, test procedure of moisture measurements, calculation and expression of results of moisture content of a lot of iron ore.
As a user of ISO 3087, you can be ensured of the moisture content in iron ore.
With ISO 3087 the user can efficiently determine and maintain the moisture content in iron ores.
What’s changed since the last update?
BS ISO 3087:2020 supersedes BS ISO 3087:2011, which is withdrawn
The main changes compared with the previous edition are as follows:
- The existing two 105 °C moisture determination methods have been confirmed to serve as a reference method
- Alternative moisture determination methods are now allowed if they can be shown to result in equivalent moisture contents as the reference methods
- The weighing device readability requirement has been changed from 0,05 % to 0,01 % equivalent of test portion mass
- Calculation and expression of results have been revised
- Annex D on examples of test reports has been updated with new example reports
